Making statements based on opinion; back them up with references or personal experience. reference them as attributes on an object named var. terraform plan -var='aad_allowed_tenants=["aasdfad"]' For many features being developed, we want our devs to spin up their own infrastructure that will persist only for the length of time their feature branch exists to me, the best way to do that would be to use the name of the branch to create the key for the path used to store the tfstate (we're using amazon infrastructure, so in our case, the s3 bucket like the examples above). not apply to child modules, where values for input variables are instead One very specific complexity with this is that currently modules need to be pre-fetched using terraform get prior to terraform plan, and currently that command does not take any arguments that would allow you to set variables.By the time plan is running, Terraform is just thinking about the module name and paying no attention to the module source, since the module is assumed to already be .

Our powershell wrapper does so many things to over come terraform restrictions, we cant use terraform without, basically we did something like the guys in terragrunt did, plus many more addons on it, i cant understand how somebody can even use terraform as is out of the box without some interpolation in those missing places.. anyhow, i really hope hashicorp will decide to change some parts of the product, because it is really constricting, some of those things should have been thought of much before. Terraform will error. If both the type and default arguments are specified, the given default peer-account = "xxxxxxxxxxxxxx" If you provide values for undeclared variables on the command line, That means they need to be provided when you run terraform init, not later when you use the backend with commands like terraform apply. You still cannot put variables in backend.conf, which was the initial question. Though this might require making such variables immutable? Is it still waiting on the proposal mentioned in this comment, #4149 ? The nullable argument only controls where the direct value of the variable may be null. Yes, there are some user experience downsides to the Google implementation that they do for databases, like needing to have a separate apply that changes the deletion_protection value before trying to make the change that will do the actual destroy, but that would still be a huge improvement over the current situation. You get around that by using terraform init -backend-config so that value is known at the beginning of the lifecycle. @mitchellh - It would be great if hashicorp could re-look at this. When multiple operators are used together in an expression, they are evaluated in the following order of operations: !, - (multiplication by -1) *, /, %.
